The african races were those races in which million years go the less developted Beings incarnated.
But: The africans will one day rise up to a high culture and then they will (most of them) fall again like
it happens and happened with each race (white,red,brown or black). The africans are the physical descendants of the fourth rootrace and some even of the fifth aryan rootrace, which includes blacks and whites. When the Beings incarnated in the african race they did not have (until that time) the karma of this race, who misused their intelligence.
The african race is a race, caused by karma, which is different from all other black and white races. Only those who study THE BOOK OF LIGHT will understand. Per definition the africans are caucasian mongolian africans. But if one thinks that caucasian or/and aryan only means white, or that aryans are only white people he must definately study THE BOOK OF LIGHT. Racism is caused by lack of esoteric knowledge. The souls of white people incarnate in black or yellow bodies and vice versa, according to karma.
The black man you may hate now, could have been your white brother in a past life. The white man you hate now could have been your black brother (or mother, sister, father of any other complexion) in a past life.
The doctrine of reincarnation, as taught in THE BOOK OF LIGHT, is the enemy of the racism and will finally return to all races and complexions or rather to those who are ready for THE BOOK OF LIGHT. AUM.
